WolfP2P browser and operating-system compatibility

Find your current browser-on-a-computer setup below. WolfP2P also runs a live capability check because support can vary by browser version, operating system, browsing mode, and organization policy.

If the live check reports a limitation, follow the result shown for the browser currently in use rather than relying on this general list.

A Compatible Browser provides the folder selection, destination-folder access, direct disk writing, and related capabilities needed for the complete WolfP2P experience. Current Chrome, Edge, and Brave are the recommended examples. Opera, Vivaldi, and other browsers built on the open-source Chromium project belong in this category only when WolfP2P's live check confirms those capabilities.

A Partially Compatible Browser can send individually selected files when the live checks permit it. Receiving in WolfP2P requires a writable destination folder. The current receiver has no memory-buffer or browser-download fallback; use a browser with the required directory access to receive files.

Without writable destination-folder access, this browser cannot receive a transfer or provide destination-based recovery in the current Product. The category describes current WolfP2P functionality, not the browser's general quality or security.

Browser support can change as browser vendors add or remove capabilities. The messages shown by WolfP2P for the current browser are therefore more authoritative than a permanent browser-version table.

For the complete WolfP2P experience, use a Compatible Browser—for example, an up-to-date Chrome, Edge, or Brave—at both ends. This setup supports choosing a complete source folder, selecting a destination folder, preserving relative paths, skipping matching destination files, and using disk-backed recovery.

The receiver's browser must let WolfP2P write directly into a chosen destination folder. Without that capability, the receiver cannot accept the transfer.

Before starting a large transfer:

1. Confirm that the sender can choose the complete source folder.
2. Confirm that the receiver can choose a destination folder. If Documents is refused with a system-files message, create and select a subfolder inside it; see folder permissions.
3. Check that the destination has enough free disk space.
4. Keep both computers awake and both tabs open.
5. Avoid private browsing when it prevents WolfP2P from retaining the file permissions needed for recovery.

Windows, macOS, and their filesystems do not accept exactly the same filename and path forms. A name that works on the sending computer may therefore be invalid at the destination.

WolfP2P checks incoming paths before creating destination files and rejects unsafe or unsupported forms. It does not silently rename them because that could create duplicate names or make the received structure differ from the source.

If a path is rejected, rename the affected source file or folder to a simple, portable name and offer the set again. When WolfP2P displays TRANSFER_DESTINATION_PATH_INVALID, use the current path-error explanation.

Your browser may help keep the screen awake during a transfer, but no browser can continue transferring while the computer is fully suspended. Closing a laptop lid, manually putting the computer to sleep, or some system power settings can still interrupt the connection.

Keep both computers awake and both tabs available until the transfer completes. See what happens when a computer sleeps for prevention and recovery guidance.

WolfP2P runs in the browser rather than through a native Windows or macOS application. Files can move between Windows and macOS when the browsers at both ends provide the capabilities required for that transfer.

Cross-platform transfer does not make every filename portable. It also does not override operating-system permissions, free-space limits, security software, or organization-managed browser policies. See Transferring Folders Between Mac and Windows for practical preparation.

The current release offers the transfer panel on computers. When WolfP2P identifies a phone or tablet, it asks you to open the same link on a computer. Public information pages remain available.

On a computer, live capability checks still determine which file operations are available. Keep the original files until the receiver has confirmed completion.
